Breakdown of Demà la meva mare tornarà de la farmàcia abans de dinar.
Questions & Answers about Demà la meva mare tornarà de la farmàcia abans de dinar.
Catalan word order is quite flexible, and time expressions are often placed first to set the scene.
So Demà la meva mare tornarà... is a natural way to say Tomorrow, my mother will return...
You could also say:
La meva mare tornarà demà de la farmàcia abans de dinar.
That is also correct. Putting Demà first just gives the time a little more prominence.
Catalan often leaves out subject pronouns when they are not needed. This is because the verb form already shows the person and number.
Here, tornarà means he/she/it will return, and the subject is already clearly stated as la meva mare, so adding ella would usually be unnecessary.
If you did add ella, it would sound more emphatic:
Demà la meva mare, ella tornarà de la farmàcia...
That is possible in some contexts, but it is not the neutral everyday version.
